Overview
Summer heat is one of the sneakiest stressors in a reef tank — a few degrees above your target temperature can push oxygen levels down and stress out fish and corals alike, often before you've even noticed the tank's running warm. The Cooling Fan System from Dymax is a simple, budget-friendly way to bring water temperature down without the cost or complexity of a full chiller.
It clips onto the edge of the tank and blows air across the water's surface, cooling it through evaporation rather than active refrigeration.
Key features
- Can reduce water temperature by roughly 2–4°C from ambient room temperature
- Simple clip-on mount that fits most aquarium edges
- Flexible, adjustable arm to angle airflow exactly where you need it
- Low power consumption compared to running a dedicated chiller
- Compact and easy to install without any plumbing
Who it's for
A great option for smaller to mid-sized reef and planted tanks where a full chiller isn't justified, or as a supplementary cooling measure during warmer months. It suits both marine and freshwater setups.
Setup & tips
- Top up evaporated water more frequently while it's running, since evaporative cooling naturally increases water loss
- Angle the flexible arm to blow across the surface rather than directly down into the water for the best cooling effect
- Keep the tank lid open or vented above the unit so it can actually move air across the surface
- Pair it with a reliable thermometer so you can judge whether it's keeping pace with your ambient temperature swings, or whether a chiller is the next step
